I dont know. Foremans has the better looking chin out of the three lol. Curvy but sharp not too edgy lol. Holyfield has a wide yet symetric chin which is pretty cool, very similar to mayweathers chin in dimension. Tyson kind of didnt have a chin it connected right with the jaw line. So I don't know... I will go with Foreman because it is the classiest chin out of the three.

Holyfield easily has a better chin than Tyson because he fought Lewis and Tyson twice and was never dropped while taking flush bombs.

Holyfield who doesn't have as much power has Tyson, dropped Tyson.

The answer is Holyfield, who has probably the best chin in HW history.

Ali wasn't featherfisted IMO. Regardless, Foreman wasn't so much knocked out by a punch but was utterly exhausted from throwing everything but the kitchen sink at Ali. By the time Ali knocked him down, there was no way he could get up because he was simply exhausted.
